If you're waiting for a big tell-all from Jason Trawick about his time with now-former fiance Britney Spears, don't hold your breath.

TMZ reports that Trawick signed a confidentiality agreement with Spears and her camp at the beginning of their relationship -- so even if he wanted to blab, he could suffer some hefty fines and legal headaches if he did.

A source close to Spears and Trawick insists that even if there weren't a contract to keep quiet in place, Trawick likely wouldn't utter a bad word about BritBrit regardless. Trawick and Spears apparently remain close despite the split, and he respects the 'Criminal' singer and erstwhile 'X Factor' judge too much to have loose lips about their love life.

Indeed, this is one of the more amicable celeb splits in recent history. Spears and Trawick reportedly broke up because they disagreed on whether to have more kids -- Spears wanted to expand her brood, while Trawick wanted to stick with just Jayden James and Sean Preston, her tots with Kevin Federline. Spears already returned her 3.5 carat Neil Lane ring, worth $90,000, to Trawick.

Here's hoping both BritBrit and Trawick can find love and happiness. We loved them together, but some things just aren't meant to be.
